Bonus Spells for High Attribute Points

The ability that governs bonus spells depends on what type of spellcaster your character is: Intelligence for wizards; Wisdom for clerics, druids, paladins, and rangers; or Charisma for bards and so on. In addition to having a high ability score, a spellcaster must be of high enough class level to be able to cast spells of a given spell level.
